Abstract
The utility model discloses a small-size four-lens stereo camera. It adopts 4 lens structures which are horizontally arranged in a word on the basis of the existing small-sized camera. 4 dark rooms are formed in the camera body corresponding to the 4 lenses. And adopts a steel sheet type shutter structure. The shutter plate is provided with 4 pairs of staggered light transmission holes corresponding to the lens, and the shutter control mechanism enables the two shutter plates to move left and right for transmitting light, thereby exposing the film. After the negative film is processed by developing, a layer of grating film is covered on the photo, thus obtaining the photo with strong stereoscopic impression.
Description
The utility model relates to minicam, relates in particular to verascope.
Existing minicam is of a great variety, and structure is different, and great majority are to use 135 or 120 films.Its structure is made of main body, film assembly, lens aperture assembly and shutter assembly and forward and backward lid, the film assembly comprises placing mechanism, mistake sheet mechanism and the rewinding device of film, camera lens is single-lens or twin-lens (have to be viewing lens in the twin-lens, phtographic lens still is).The aperture assembly has plenty of adjustable, have plenty of fixing, the shutter assembly is made of control gear and tripper, tripper generally adopts steel disc formula tripper, the steel disc that has a hole above it is pasted mutually by two front and back constitutes, and the installation of staggering about the hole of being opened utilizes control gear to make about shutter disk and relatively moves, make the hole of being opened just in time corresponding to camera lens, to realize exposure.The shutter assembly also is divided into adjustable speed and fixed two big classes.These cameras can also increase some as mechanisms such as flashlamp, the rewinding device that rewinds, automatic light measuring, continuous shooting, auto heterodyne, camera lens are flexible automatically, to improve automaticity, image quality and to improve effect.
These cameras so the picture of breaking forth all is the two-dimensional plane image, do not have stereoscopic sensation owing to have only a phtographic lens, though also the someone proposes the raster film of cover tape ripple on two-dimensional image, to strengthen stereoscopic sensation, its effect is unsatisfactory.
The purpose of this utility model provides a kind of small-sized four-barrel stereocamera, forms the slightly image of difference of a plurality of visual angles, the photograph that can obtain to have very strong stereoeffect after developing and printing processing by these camera lenses on negative film.
The purpose of this utility model is achieved in that the upright position of a small-sized four-barrel camera, includes view finder, film assembly, they all are installed on the camera body.At the main body middle part one bigger cavity is arranged, open and form four darkrooms in the cavity, at the rear portion of main body the corresponding camera bonnet is housed, be used for dress and get film, four photographic lenss of word order are installed in the front portion of main body, and they are fixed on the main body by lens bracket, each photographic lens respectively with four darkrooms, correspondence is equipped with the protecgulum of window greatly in body front end, and said window is corresponding with photographic lens.The shutter assembly also is installed, with the exposure of control to negative film on main body.
The utility model will be further described below in conjunction with accompanying drawing.In the accompanying drawings, Fig. 1 is an optical axis cross section view of the present utility model, and Fig. 2 is camera lens of the present utility model, aperture, shutter structure synoptic diagram.Wherein (1) is that lens, (2) are that camera lens frame, (3) are that lens bracket, (4) are that iris diaphragm plate, (5), (6) are that shutter disk, (7) are that main body, (8) are that negative film, (9) are that darkroom, (10) are protecgulums.With reference to the accompanying drawings, photographic lens is made of 4 lens (1) that are fixed on the camera lens frame (2), and it is fixed on the front end of camera body (7), the preferably horizontal word order of photographic lens by lens bracket (3).Each camera lens back is equipped with iris diaphragm plate (4), 4 diaphragm holes on the iris diaphragm plate (4) are corresponding one by one with 4 camera lenses respectively, iris diaphragm plate (4) back then is equipped with shutter disk (5), (6), have light hole on two shutter disks (5), (6), make the installation of staggering of light hole on two shutter disks (5), (6), shutter disk (5), (6) are by the shutter control mechanism gauge tap, and control gear can be with the identical structure of existing steel disc formula tripper.When the shutter system of pressing was pulled, control gear made about shutter disk (5), (6) and relatively moves, and made light hole just in time aim at 4 photographic lenss respectively.Iris diaphragm plate (4) and shutter disk (5), (6) all are mounted on the main body (7), and the rear portion of main body (7) is formed with and 4 photographic lenss darkroom (9) one to one.The width in 4 darkrooms (9) should just in time equal the width of two standard negative films, so can obtain satisfied image.
The utility model is simple in structure, its roll film assembly, aperture device and shutter control mechanism all can adopt existing structure, also can increase existing minicams such as some automatic light measuring mechanisms, flashlamp are installed structure commonly used,, improve automatization level to improve its function.
The utility model adopts the eyes effect principle, takes simultaneously with 4 identical camera lenses, obtains the slightly different negative film of 4 subtended angle degree.These several negative films are amplified on the printing paper in order, cover the raster film of one deck band ripple then, and can obtain one has strong relief photo.
Claims (2)
1, small-sized four-barrel stereocamera, include view finder, film assembly, it is characterized in that being equipped with the camera body of view finder and film assembly, have a bigger cavity at said main body middle part, in cavity, form 4 darkrooms, at the rear portion of main body the corresponding camera bonnet is housed, be used for dress and get film, the photographic lens of word order is installed in the front portion of main body, they are fixed on the main body by lens bracket, each photographic lens is corresponding with 4 darkrooms respectively, controls its exposure by the shutter assembly, and the protecgulum of big window is installed at the front end of main body.
2, small-sized four-barrel stereocamera according to claim 1 is characterized in that preferably horizontal word order of said photographic lens, and Dui Ying darkroom also is to form horizontally in cavity with it.
